Amphenol glass toslinks - First impressions

I just got my Amphenol glass toslink cables. I have done a quick a/b between it and a basic $5.00 fiber toslink .
The detail is very noticable right off the bat. There seems to be greater hang time on the steel guitars, the brush on the snare is more defined and the texture of the electronocs is more distinct. The soundstage seems to be deeper also. The vocals and instruments that are far back also are not muddy, but very clear and crisp.
In my opinion they do make a definite difference over the standard fiber cables that I have been buying elsewhere.

Anyone else notice that difference when changing to glass?
